This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1909 edition. Excerpt: ... worn pelage: Sides and upperparts nearly uniform cinnamon rufous, with scarcely any dusky admixture and only a narrow line on back somewhat deeper colored than rest of upperparts. Immature: As in adult, but grayer. Skull.: --Rather small and light; braincase relatively narrow; nasals and palatine slits short; molar teeth small; otherwise similar to P. l. mesomelas. Measurements.--Average of 10 adult topotypes: Total length, 163 (156-169); tail vertebrae, 73 (68-79); hind foot, 21.5 (20-22); ear from notch (dry), 12.5 (11.3-13.6). Type specimen.--No. 107980 U. S. National Museum, Biological Survey Collection. $ adult. December 19, 1900. E. W. Nelson and E. A. Goldman. Specimen practically perfect. Remarks.--P. l. castaneus is slightly darker than P. l. cozumelae, which is closely related. P. cozumelae differs chiefly in larger size and heavier teeth. No satisfactory specimens from the humid tropical region between Orizaba and Yohaltun are at hand, but castaneus is not sufficiently different from mesomelas to warrant full specific rank. P. affinis is a related form of the adjacent arid tropics, and much paler than either castaneus or mesomelas. Specimens examined.--Total number 25, all from the type locality.
